Abstract: a well trained teacher who is fluent in adult education as a change agent responsibility is beyond routing plans and activities, In recent years the practice has changed and the role of educator as a "change agent" and reform as a donor and an "auxiliary roles" or "facilitators" were raised as his understanding of adult personal and community among people. In addition, a person well trained teacher who is fluent in adult education as a change agent responsibility is beyond routing plans and activities. His role in the educational process as a facilitative (helpful), leader (leading), incentives, consultant and source of information (not move), regular (planned), judge poster and..... Is. The ultimate goal of people helping him to his ability to help raise up to be adult. Fact that the adult educator role of a marginal position in society has changed to a central location for this position change the natural outcome of many social problems such as wars, crime, illiteracy and disease.... Can easily be resolved through processes of adult education.

Abstract: In this work, a set of seven hydrazone derivatives were worked on using quantum chemical method and many molecular descriptors were obtained so as to probe in to their biological activities. Also, docking study was carried out on the studied compounds against the C. albicans cell line (receptor) 1q42 in order to obtain binding energy as well as to observe the interaction between them. The studied compounds were compared with Clotrimazole as standard drug. The order of binding energy of each molecule with the receptor is AB7<AB1<AB5<AB6=AB4<AB3<AB2. AB7 was observed to inhibit better than the Clotrimazole that was used as standard.

Abstract: In this paper we present a procedure for prominent point's resolution based on color prominence. Prominent points are locations in an image where there is a significant variation with respect to a chosen image feature. Since the set of prominent points in an image capture important local characteristics of that image, they can form the basis of a good image representation. Prominent features are generally determined from the local differential structure of images. They focus on the shape prominence of the local neighborhood. Most of these detectors are brightness based which have the problematic condition that the distinguishing feature of the local color information is completely ignored in determining prominent image features. To fully take advantage of the possibilities of prominent point detection in color images, color distinguishing feature should be taken into account in addition to shape distinguishing feature. The color and texture information around these points of interest serve as the local descriptors of the image. In addition, the shape information is captured in terms of edge images computed using Gradient vector flow fields. Constant moments are then used to record the shape features. The combination of the local color, texture and the global shape features provides a strong feature set for image restoration. The experimental results exhibit the efficacy of the procedure.

Abstract: One of the important relationships between classes in UML is inheritance relationships. Since there are few techniques for modeling and analyzing UML, by formalizing class diagram – as important section of UML – in this paper, after converting one system to class structure in UML, we present a solution for Establishment of inheritance relationships in UML. Also we can reduce complexity of each class in the system. Then by modeling this structure by this solution it will be prepare for some goals such as verifying and validating. By using an example we show procedure of formalizing the system. After all, we come to a conclusion that formal method improves ability of analyzing and implementing a system. By improving these factors, we can get better results in other techniques such as formal verification and validation and software testing.

Abstract: During 1980s there was a debate between formalists and functionalists concerning the issue of language acquisition. The former dealing with issues of learnability and a hypothesized ‘mental organ of language’, and the latter focusing upon the significance of social interaction and general cognitive principles in the acquisition process. The proponents of the formal approaches to language acquisition are called adaptationists as they believe that language learners are equipped with general principles of grammar in advance and their task as language learners is to adapt these principles to fit the data he/she is exposed to. On the other hand, the advocates of functionalist perspective are called constructionists as they hold that learning a language entails constructing a grammar during the process of language learning. There are two main senses of the term functional. At the most basic level, functional work is concerned with possible mapping relations between linguistic form and semantic or pragmatic functions. This descriptive orientation is called relational functionalism. There is an alternative approach to relational functionalism called ecological functionalism. It is concerned with providing explanations about language which show that recurring patterns of relational mappings or the historical or developmental changes in a grammar are due to general constraints on possible grammars which arise from the naturally occurring circumstances of human discourse interaction and the cognitive processes associated with them. Such explanations argue that systemic changes (historical or developmental) are associated with making discourse easier to comprehend or with grammaticalizing certain functional principles in order to automate production efforts. The current paper delves into the intricacies of this new approach to functionalism and offers that it can be a legitimate alternative to relational functionalism.

Abstract: Session Initiation Protocol (SIP) is a powerful signaling protocol that increasingly used for administrating Voice over IP (VoIP) phone calls. SIP authentication mechanism is based on HTTP Digest authentication, which this scheme is insecure; such as off-line password guessing attacks and impersonate other parties and etc. So proposed different schemes to secure the SIP authentication. In the year 2012, Tang et al. proposed a SIP authentication protocol using elliptic curve cryptography (ECC), but their scheme is insecure against off-line password guessing. We proposed an ECC-based authentication scheme for SIP to overcome such security problems and analysis of security of the ECC-based protocol.

Abstract: The rate of asset return and growth in sales is considered as an index for measuring the financial performance of companies in supplying their operational efficiency. The main goal of many companies is to access higher rate of asset return. Additionally, managers and analysts of the companies widely rely on the rate of asset return and the rate of the growth-in-sales as a criterion for measuring the performance of the companies. If the companies who adopt cost leadership strategy can be successful in using the least assets to reach their commercial results, then the performance of the company will be promoted [5]. As a survey, this study aims to investigate the selected strategy of the companies and its relationship with their financial performance in a period of 7 years (2005-2011). This research has been conducted on 30 companies out of the top 50 public companies of Tehran Stock Exchange. The results show that applying the cost management strategy has had a direct effect on the financial performance of the companies and has led to the improvement of their performance in short terms.

Abstract: In recent years, Wireless Sensor Networks (WSNs) have been emerged as potential challenges in wireless communications. Wireless sensor network consists of the low-cost, low-power, and large-scale wireless sensor nodes. Routing protocols and different mechanism for transmitting data are the principal topics in WSN. In this paper, we propose a new QoS-based data forwarding scheme (QFD) with Wireless sensor network to monitor the environmental conditions. We split whole surface of the environment into several areas. Each area contains information about the environmental status. All sensed data in the areas are transmitted to related cluster head; then they are forwarded to the nearest sink. We use from two sinks in the suitable positions and perform the internal routing by proposed Smart Inner Routing Algorithm (SIRA) for routing data from the cluster heads to the related sink. Furthermore, we propose a Binary Recursive Convergent (BRC) algorithm for data aggregation in the areas. Simulation results show that remainder energy of the sensor nodes is balanced, partly. The performance of the proposed method is compared to DSR protocol. Simulation results illustrate that the proposed method in average delivery ratio, average delay time, network lifetime, consumption energy of nodes, and network traffic is better than other protocol.

Genome Editing and Cancer Research Literatures

Abstract:. Genome editing, or genome engineering is a type of genetic engineering in which DNA is inserted, deleted, modified or replaced in the genome of a living organism. In 2018, the common methods for such editing use engineered nucleases, or "molecular scissors". These nucleases create site-specific double-strand breaks (DSBs) at desired locations in the genome. The induced double-strand breaks are repaired through nonhomologous end-joining (NHEJ) or homologous recombination (HR), resulting in targeted mutations. As of 2015 four families of engineered nucleases were used: meganucleases, zinc finger nucleases (ZFNs), transcription activator-like effector-based nucleases (TALEN), and the clustered regularly interspaced short palindromic repeats (CRISPR/Cas9) system. Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread to other parts of the body. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss and a change in bowel movements. While these symptoms may indicate cancer, they may have other causes. Over 100 types of cancers affect humans. This article introduces recent research reports as references in the related studies.
